PRODUCTION, CHARACTERISTICS AND USE OF

2015-5-22  The ferroalloy separation from the lumpy slag happens in a special process, which is based on a gravity and magnetic separation. The first stage of slag processing is crushing and sc reening the feed material to fractions of 0-4 and 4-22 mm. Coarser fractio ns are handled by a heavy media separation - the DWP-method. A magnet

Ferrochrome - an overview ScienceDirect Topics

The most common recovery process is to crush the slag (in the case of the first slag-handling method) and recover the alloy particles in a wet jigging process. In particular cases where the high carbon ferrochrome is sufficiently magnetic, magnetic separation techniques can also be applied. The quality of the product from the recovery process ...

Up-Concentration of Chromium in Stainless Steel Slag and ...

Slags coming from stainless steel (SS) and ferrochromium (FeCr) production generally contain between 1 and 10% Cr, mostly present in entrapped metallic particles (Fendash;Cr alloys) and in spinel structures. To recover Cr from these slags, magnetic and gravity separation techniques were tested for up-concentrating Cr in a fraction for further processing. In case of SS slag and low carbon (LC ...

2005-1-6  The slag crushed to −10 mm was subjected to three-stage magnetic separation at around 800–1000 G. The final magnetic fraction was then subjected to sink–float tests. It was possible to recover only 1.1% of metal with 59% chromium (Sripriya et al., 1996). Subsequently, large-scale magnetic separation and jigging tests were also carried out.

Samancor Products - Samancor Chrome

To improve total ferrochrome recovery while maintaining a high-quality product, alloy recovery plants are utilised to recover the ferrochrome from the slag produced during the charge chrome process. The slag, which has a metallic content of approximately 4 percent, is processed through a series of crushers and broken down to minus 15mm material.
